Abstract:

In the promotion and development of renewable energy systems, control engineering is one area which can directly affect the overall system performance and economics and thus help to make renewable energies more attractive and popular. For cost effectiveness, ideally the renewable energy industry requires a control design technique which is very effective yet simple with methods that are transparent enough to allow implementation by non-control engineers. The objective of this thesis is to determine if Model Based Predictive Control (MBPC) is a suitable control technique for use by the renewabl

Due to the rising demand of energy over several decades, conventional energy resources have been continuously and drastically explored all around the world. As a result, global warming is inevitable due to the massive exhaust of CO2 into the atmosphere from the conventional energy sources. This global issue has become a high concern of industrial countries who are trying to reduce their emission production by increasing the utilization of renewable energies such as wind energy.

Abstract:

The problem of predicting weather variables, such as solar radiation and wind speed, is of great interest for integrating renewable energies plants, into the electric grid. Indeed, since renewable energy sources are intermittent in nature, predicting future values is important to allow the grid to dispatching generators, in order to satisfy the demand. There are essentially two ways to address the issue of weather variables prediction. One is by using Numerical Weather Forecasting (NWF) models, which are reliable, but also quite complex and requires real time information, usually available fro

Abstract:

Sustainable energy solutions are aimed to reduce the consumption of fossil fuels by using renewable energy sources and energy efficiency techniques. This thesis presents two new sustainable energy applications in the field of electrical machines.Polyphase induction motors dominate the energy usage spectrum for industrial and commercial applications. The conventional winding structure used in both synchronous and induction machines has a basic unit of the winding with a 60 degree phase belt and a three phase connection either in star or delta. A new winding structure using an innovative Star-De

Abstract:

As wind energy penetration levels increase, there is a growing interest in using storage devices to aid in managing the fluctuations in wind turbine output power. Vanadium-Redox batteries (VRB) and Lithium-Ion (Li-Ion) batteries are two emerging technologies which can provide power smoothing in wind energy systems. However, there is an apparent gap when it comes to the data available regarding the design, integration and operation of these batteries in wind systems. This thesis presents suitable battery electrical models which will be used to assess system performance in wind energy applicatio

Abstract:

Wind generation has become the most important alternate energy source and has experienced increased growth in Europe during the past decade while more recently, the same trends have been exhibited in North America. Although it has great potential as an alternative to less environmentally friendly energy sources, there are various technical challenges that cause wind to be regarded negatively by many utilities. Others are hesitant to accept its widespread implementation, particularly when the penetration of wind in a given area is high.<br>This work presents the addition of an energy stor

Abstract:

In several areas around the world, clean water is a precious asset that at anytime, and mainly due to circumstances of weather and climate, can become scarce. Mainly in the dry and remote places, people suffer with lack of water. A solution for this suffering can be a water desalination system, which makes water potable and usable for industry. That solution inherently, brings the problem of power requirement, which is sometimes arduous to accomplish in such remote areas of difficult access and long distances to overcome to build the infrastructure required to operate an electric power plant.

Abstract:

La promotion de l’énergie éolienne comme une alternative viable et compétitive aux sources traditionnelles est dépendant du développement des techniques de modélisation avancées qui vont diminuer à la fois le coût de l’énergie et l’incertitude reliée à son évaluation. D’une importance particulière dans cet effort est l’amélioration des outils d’évaluation de la production des projets éoliens. Bien que des modèles linéarisés ont dominé ce domaine dans le passé, les modèles basés sur les équations de Navier–Stokes moyennées (RANS) sont de plus en plus populaires, surtout pour les sites difficil
